<span id="object-gateway"></span><h1>Ceph 对象网关<a class="headerlink" href="#ceph" title="Permalink to this headline">¶</a></h1>
<p><a class="reference internal" href="../glossary/#term-14"><span class="xref std std-term">Ceph 对象网关</span></a>是个对象存储接口，在 <code class="docutils literal notranslate"><span class="pre">librados</span></code> 之上为应用程序构建了一个 RESTful 风格的 Ceph 存储集群网关。
<a class="reference internal" href="../glossary/#term-13"><span class="xref std std-term">Ceph 对象存储</span></a>支持 2 种接口：</p>
<ol class="arabic simple">
<li><p><strong>S3-compatible:</strong> 提供了对象存储接口，与亚马逊的 S3 RESTful
风格的接口兼容。</p></li>
<li><p><strong>Swift-compatible:</strong> 提供了对象存储接口，与 OpenStack 的
Swift 接口兼容。</p></li>
</ol>
<p>Ceph 对象存储使用 Ceph 对象网关守护进程（ <code class="docutils literal notranslate"><span class="pre">radosgw</span></code> ），它是个与 Ceph 存储集群交互的 FastCGI 模块。因为它提供了与 OpenStack
Swift 和 Amazon S3 兼容的接口， RADOS 要有它自己的用户管理。
Ceph 对象网关可与 CephFS 客户端或 Ceph 块设备客户端共用一个存储集群。 S3 和 Swift API 共用一个通用命名空间，所以你可以用一个 API 写、然后用另一个检出。</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>Ceph 对象存储<strong>不</strong>使用 Ceph 元数据服务器。</p>
